Abstract: PURPOSE:To make it possible to surely reduce the diameter of a block. CONSTITUTION:The peripheral surface section of the base end of a block 22 is inclined so that it is gradually separated from the axis of a device 10 with the movement to the front end side of the block 22. In a state to widen a diameter of the block 22, the site of the base end side of the block 22 forms an inclined surface 22k positioned to the inside of a radial direction of a casing pipe 30 from the end thereof. When the block 22 is drawn up, the front end of the casing pipe 30 is brought into contact with the inclined surface 22k to exert a upward force to the surface, the component of the pressing force is directed to the axis side of the device 10, so that force (component of the pressing force) in addition to turning effort of the device 10 is acted on the block 22 through the inclined surface 22k. Accordingly, excavated waste held between straight ends is crashed to remove, so that diameter reduction can be surely made.

Filed: 1989-05-29
Abstract: PURPOSE:To improve withstand voltage without widening the distance between electrodes by making the shape of rims of electrodes placed in opposite each other and composing a focusing lens. CONSTITUTION:Two electrodes 13, 13 composing a focusing lens are placed in opposite each other and rims 2, 2 are formed in the tips of the electrodes.

Title: Oscillating method for wire rod coil
Inventor: KAWAKAMI HEIJIROU
IPC: C23G3/00
Filed: 1978-11-01
Abstract: PURPOSE: To rotate the coil-shaped wire rod in the pickling solution suspending on the hook as it is and to carry out a uniform treatment, by attaching the rotary vibrator to the beam and carrying out circular oscillation in the plane crossing at right angles to the longish direction of the beam.  
     CONSTITUTION: The rotary vibrator 9 is attached along the longish direction of the beam 2 supportd on the buffer 8, such as spring etc. The wire rod coil 1 is suspended on the hook 3 fixed on the beam 2. When the upward and downward direction force is generated by the vibrator 9, the above force is transmitted to the coil 1 if the sufficient rigidity of the suspension hook 3 is kept and the coil 1 is moved in upward and downward direction. When the left and right direction force is generated, support point of the coil 1 is moved in the left and right direction by rotation moment because the point of gravity center of support system is displaced. Hereby, the coil 1 is treated in the pickling solution etc. suspended by the hook 3 as it is.

Title: Converting circuit of switch information
Inventor: SASAKI YASUHIKO
IPC: H03K17/00
Filed: 1984-06-29
Abstract: PURPOSE:To select a desired number by one-touch by latching switch information from a non-lock pushbutton switch to a set/reset flip-flip (SR-FF), using the latch information to light a light emitting diode and applying the result to a D-FF and sampling the D-FF with a clock. CONSTITUTION:The switch information generated by depressing one switch among plural pushbutton switches in a switch section 10 is latched by the SR-FF corresponding to the SR-FFs in an SR-FF section 12 comprising plural SR-FFs. The information lights a light emitting diode corresponding to light emitting diodes in a light emitting diode section 13 and is fed to a D-FF section 13 and a reset section 14. The reset section 14 transmits the reset information to the SR- FF section 12 to clear the other SR-FFs than the corresponding SR-FF corresponding to the depressed pushbutton switch. On the other hand, the D-FF section gives an output externally while being sampled by a clock from a clock generating section 15. Further, the phase of the sampling of the D-FF is shifted so as not to prevent two outputs from being given from the D-FF section 13.

Title: Input device
Inventor: ODAGIRI NOBUO
IPC: H03M11/10
Filed: 1986-06-11
Abstract: PURPOSE:To obtain an input device which makes the input smooth as well as reduction of the number of keys by outputting different codes according to the pushing frequency of the same key within a fixed time. CONSTITUTION:When input mode keys 2 and 3 are pushed on a keyboard 1, a timer means 4 starts counting the time for a fixed period. A switch means 10 outputs a key code only when the means 4 finishes its time counting action. The selection of output codes is carried out in response to the output of a comparing means 8. Thus the means 10 selects the output of a key code generating means 9 when the coincidence is obtained from comparison of the means 8 and then selects the output of a memory means 7 when no coincidence of comparison is obtained from the means 8 respectively. Therefore a key code of small alphabet letters is outputted if the key 2 is continuously pushed within a fixed period from the first push of the key 2. While a KANA (Japanese syllabary) code is delivered if the key 2 is not pushed continuously or the other key 3 is pushed. In the same way, a KATAKANA (square form of Japanese syllabary) code and an alphabet capital code are delivered with a single push and continuous pushes of the key 3 respectively.
